Saved queries have been one of the overlooked features in the admins toolbox.

You can save queries to search for disabled user or computer accounts, number of days since the last user logon, users with non-expiring Passwords, and many other commonly used queries. All queries located in the Saved Queries folder are stored in Active Directory Users and Computers (dsa.msc). Once you have successfully created your customized set of queries you can copy the .msc file to other domain controllers (located in the same domain) and use the same set of saved queries. You can also export saved queries to an .xml file and import them into other Active Directory User and Computer consoles located on domain controllers (within the same domain).

To get started go to Active Directory Users and Computers:

Right click the Saved Queries folder and select New, Query.
Enter an appropriate Name and Description.
Make sure the query root is set to the domain level you want the query to pertain to.
Select the Include sub-containers check box if you want the query to search all sub-containers.
Click Define Query.
In the Find dialog box, click the Find drop-down arrow and select Custom Search.
On the Advanced tab, enter your LDAP query string into the Enter LDAP query box.
Click OK twice.

Some LDAP query examples:
Users whose accounts are disabled
(&(objectCategory=person)(objectClass=user)(userAccountControl:1.2.840.113556.1.4.803:=2))

(objectcategory=group)(samaccountname=*admin*)

Find users who have admin in description field
(objectcategory=person)(description=*admin*)

Groups with No Members (finds groups that have no members in them)
(objectCategory=group)(!member=*)
Note: The ! symbol means “Not” and * means “Has a value,” so the combination of the two evaluates to “Doesn’t have a value.”

(groupType:1.2.840.113556.1.4.804:=14)

(objectCategory=person)(objectClass=user)(!useraccountcontrol:1.2.840.113556.1.4.803:=2)

(sAMAccountType=805306369)

Find all 2003 Servers Non-DCs
(&(&(&(samAccountType=805306369)(!(primaryGroupId=516)))(objectCategory=computer)(operatingSystem=Windows Server 2003*)))

Find all 2003 Servers – DCs
(&(&(&(samAccountType=805306369)(primaryGroupID=516)(objectCategory=computer)(operatingSystem=Windows Server 2003*))))

Find all Server 2008
(&(&(&(&(samAccountType=805306369)(!(primaryGroupId=516)))(objectCategory=computer)(operatingSystem=Windows Server 2008*))))

One of the other features I like to enable is the Status option within ADUC.  It will provide a total of all the objects in the ADUC window.

Next time we will look at AD Administrative Center the new ADUC well kinda.
